Important Note from Mrs. B!

In organisms, the total of all the reactions going on is called metabolism. Exothermic reactions are called catabolic reactions (let the "cat" out of the bag!) and endothermic reactions are called anabolic reactions.

(Didn't want to make you read a whole CK12 for that!)
